Mike Recapitulating: The D&RG class 125s, later D&RGW K-27s, were built in 1903 with saturated steam boilers and Vauclain compound cylinders worked by inside Stevenson valve gear and inside piston

The basic framing is in and I've started the road bed. I use splines by sandwiching short blocks between 1/8 th by 1 inch laths. I cut the laths from 1/8th inch doorskin sheets. The blocks are 1

Graeme: When first issued, the kits differed only in the body bolster that was included. One contained an HO standard gauge bolster, and the other an HOn3. Later, they included both in the same kit

A quick look through the two kits and I believe it is only in the trucks. SG wheel sets for all axles. Different tender truck bolsters and the rotary has different side frames (missing the

Gee that was easy, just needed to look a bit closer at the pics. #30 is HOn3 #31 is HO Graeme

Quick question, what is the difference between DP kit 30 & 31? From photos online it looks like kit 31 has more metal detail parts both seem to be based on OM Thanks Graeme Walker Toowoomba Australia

SO I have a question about an earlier evolution of these locos: conversion from compound to slide valve, and when the slope-back tenders were replaced. I thought they were coincident, but I've seen a

Thanks for the link Sebastien The discussion was so informative that I had to update my copy of O'Berry's "Mudhens"! http://ngdiscussion.net/phorum/read.php?1,378057,page=1 John Stutz

450, 451 and 457 along with 460 were never converted to piston valves and Walschaerts Valve Gear. They were converted to single expansion slide valves around 1908 retaining their Stephenson Valve

I believe the 460 was the only K-27 that was never converted to walschaerts valve gear. The 462 had no super heater. After contuous shopping, no two K-27's wound up having the same arrangement of

That was Brewster.

Ed Knoob, Prefect. Thanks for the precis. Priceless. Mark K

Earl and Seb, Thanks, that was just the information I was looking for. It's amazing what a wealth of information there is here on these forums. Thanks again all. Scott

Ed, Thanks for the offer. You can send them to ftgc AT comcast DOT net. Scott

In a nutshell: 454, 456, 458, 461 received piston valve conversions in the late 1910's retaining Stephenson Valve Gear and saturated steam. To connect with the existing valve gear, the valve chests

Model Railroader did a 2 part series on the K27. March and June 1973. I have it as 11 .pdf’s if you want give me your email address. Ed T.

Hi guys, Last autumn I started a thread on the NGDF forum about the K27 valve conversions. Very good informations were given, by Earl Knoob for example (costs, dates, etc...). The discussion also

Blackstone models has a believable story at: Blackstone Models Blackstone Models

So is it safe to say that by the late 1920s most of the fleet had been converted to cylinder pistons and Walschaerts valve gear? The reason I'm asking is that I'm thinking of changing the period of

You will find it was done over a period of time and gradually as the locomotives were shopped over a period of several years DEC Look for a copy of “The Mudhens” by Dennis O’Berry too. --
